| Abstract: | According to both the general formula of ground surface displacement by drainage from a well for radial permeable flow of
underground water and the drawdown expressions for the flow in multilayered structural aquifers, we have derived the analytical
expressions of surface displacement induced by steady flow withdrawal from a full penetrating well on phreatic water and confined
water in multilayered structural aquifers and discussed the numerial integration scheme of these analytical expressions. And
by means of Hermite’s quadrature formula with 20 nodes, we have made calculational programs and examples to show that the
methods mentioned in this paper are effective. We think that these methods lay a foundation to study quantitatively crustal
deformation due to groundwater drainage when we are engaged in high precision dynamic geodetic measurement on the area of
steady flow of multilayered aquifers. |
